Know before you buy
These bulbs should be planted in the fall before the ground freezes. This allows them to establish roots during the cooler months so they are ready to bloom in early spring.
Yes, they are excellent for naturalizing in lawns. For the best results, plant them in areas where you can delay mowing until the foliage has turned yellow and died back, which ensures the bulbs store enough energy for next year's blooms.
Yes, Yellow Mammoth Dutch Crocus are considered deer resistant. While no plant is entirely deer-proof if food sources are scarce, these are generally ignored by deer and other common garden pests.
Plant your bulbs approximately 3 inches deep. This depth provides enough insulation for the bulbs while allowing them to emerge easily when spring arrives.
Absolutely. They are well-suited for containers, making them a great choice for porch pots or window boxes. Ensure your container has good drainage to prevent the bulbs from rotting during the winter.
They perform best in full sun to partial sun. While they can handle some shade, planting them in a spot that receives at least a few hours of direct sunlight will result in the most vibrant, reliable blooms.
